PayPal-PHP-SDK 无法使用列表中的单个项目

Question

我正在关注 this example 并在 Laravel 应用程序中使用它。在测试期间，我注意到当我将仅包含单个项目的数组传递给 $itemList->setItems($items); 我收到以下错误：Got Http response code 400 when accessing https://api.sandbox.paypal.com/v1/payments/payment

这是我正在使用的代码片段：

    $card = new CreditCard();
    $card->setType("visa")
        ->setNumber("4669424246660779")
        ->setExpireMonth("11")
        ->setExpireYear("2019")
        ->setCvv2("012")
        ->setFirstName("Joe")
        ->setLastName("Shopper");
    $fi = new FundingInstrument();
    $fi->setCreditCard($card);
    $payer = new Payer();
    $payer->setPaymentMethod("credit_card")
        ->setFundingInstruments(array($fi));
    $items[0] = new Item();
    $items[0]->setName('Ground Coffee 40 oz')
        ->setDescription('Ground Coffee 40 oz')
        ->setCurrency('USD')
        ->setQuantity(1)
        ->setTax(0.3)
        ->setPrice(7.50);
   /* 
    Removing this comment makes this code work
   $items[1] = new Item();
    $items[1]->setName('Granola bars')
        ->setDescription('Granola Bars with Peanuts')
        ->setCurrency('USD')
        ->setQuantity(5)
        ->setTax(0.2)
        ->setPrice(2); */

    $itemList = new ItemList();
    $itemList->setItems($items);
    $details = new Details();
    $details->setShipping(1.2)
        ->setTax(1.3)
        ->setSubtotal(17.5);
    $amount = new Amount();
    $amount->setCurrency("USD")
        ->setTotal(20)
        ->setDetails($details);
    $transaction = new Transaction();
    $transaction->setAmount($amount)
        ->setItemList($itemList)
        ->setDescription("Payment description")
        ->setInvoiceNumber(uniqid());
    $payment = new Payment();
    $payment->setIntent("sale")
        ->setPayer($payer)
        ->setTransactions(array($transaction));
    $request = clone $payment;
    try {
        $payment->create($apiContext);
    } catch (Exception $ex) {
        ResultPrinter::printError('Create Payment Using Credit Card. If 500 Exception, try creating a new Credit Card using <a href="https://ppmts.custhelp.com/app/answers/detail/a_id/750">Step 4, on this link</a>, and using it.', 'Payment', null, $request, $ex);
        exit(1);
    }
     //ResultPrinter::printResult('Create Payment Using Credit Card', 'Payment', $payment->getId(), $request, $payment);

    return $payment;

在哪里，如果我取消注释 $items[1] 部分，它工作正常。为什么会这样？

Answer 1

它抛出 400 异常，因为总数不匹配。您可以使用正确的消息捕获正确的异常，如下所示： https://github.com/paypal/PayPal-PHP-SDK/wiki/exception-%27PayPal%5CException%5CPayPalConnectionException%27-with-message-%27Got-Http-response-code-400-when-accessing

try {
    $payment->create($apiContext);
} catch (PayPal\Exception\PayPalConnectionException $ex) {
    echo $ex->getCode(); // Prints the Error Code
    echo $ex->getData(); // Prints the detailed error message 
    die($ex);
} catch (Exception $ex) {
    die($ex);
}

在您的情况下，因为您删除了第二项，所以总数不匹配。用适当的值替换下面的代码，它应该可以工作。

   $details->setShipping(1.2)
        ->setTax(1.3)
        ->setSubtotal(7.8);
    $amount = new Amount();
    $amount->setCurrency("USD")
        ->setTotal(10.3)
